Proflow's AirDual intake manifold is engineered for optimal performance on street 253-304-308 c.i.d. Holden Commodore V8 engines, offering the pfem2194 proflow intake advantage to enthusiasts and daily drivers alike. The dual-plane design is carefully tuned to provide excellent throttle response from idle to 5500 RPM. This refined tuning not only improves fuel vaporisation but also significantly enhances volumetric efficiency, making the engine more responsive and efficient under varying conditions.

Precision engineering ensures that the intake is compatible with both early and late cylinder head bolt hole patterns. It features pilot holes drilled on each side of the exhaust crossover, facilitating a seamless installation process. Additionally, it accommodates both square-bore and square spread bore carburetors, further emphasizing its versatile design and compatibility across multiple engine setups.

Designed to fit Red, Blue, and Black engines without adaptation, the intake manifold is available in either natural or black powder-coated cast-aluminium finishes, allowing users to choose the style that best suits their engine bay aesthetics. While it does not include a provision for an external heat crossover, its overall design consistently prioritizes streamlined performance and ease of installation.

The inclusion of a square bore adaptor plate enhances the manifold's flexibility and ease of use, rounding out a product that delivers tangible performance improvements for the Holden Commodore community.
